TRIP FOR LITTER-CARRIERS.

Application filed August 26, 1915.

To all whom it may concern:

Be it known that I, MALCOLM B. MoYnR, a citizen of the United States, residing at Montevideo, in the county of Chippewa and State of Minnesota, have invented certain new and useful Improvements in Trips for Litter-Carriers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in trips used upon the tracks of litter carriers for the purpose of engagement with an additional trip on the carrier proper to release the tilting bucket at the proper time. For this purpose, heretofore, it has. been common practice to provide a sheath or slide movable longitudinally upon the track and carrying a trip which, when engaged by the trip on the carrier, grips the track and is thus held against further movement. The main difficulty encountered with devices of this class, has been that strong winds often blow the trip on the track laterally to such an extent as to position it out of alinement with the trip on the carrier, thus preventing dumping of the bucket at the proper time. It is therefore the object ofmy invention to provide a device which will overcome the difliculty in question. To this end, I provide" certain novel features of construction to be hereinafter fully described and claimed, the

descriptive matter being supplemented by the accompanying drawings wherein:

Figure 1 is a side elevation of a trip constructed in accordance with the invention, illustrating the application thereof to use; Fig. 2 is a bottom plan view, and Figs. 3 and 4 are vertical transverse sections as seen on the planes of the lines 3-3 and M of Fig. 1 respectively.

In this drawing which constitutes a part of the application and in which like reference characters designate corresponding parts throughout the several views, the numeral 1 indicates broadly the sheath which is shiftable longitudinally upon the usual overhead track 2, the latter being of any preferred formation, usually a cable, but often a rod.

The sheath 1 is formed of a single elongated metal plate bent upon itself at its longitudinal center to provide an elongated archfor the reception of the track 2, and a pair of side flanges 4 depending from opposite Specification of Letters Patent.

Serial No. 47,486.

sides of the arch. The intermediate portions of the flanges 4 are parallel as clearly disclosed in Figs. 2 and 3, whereby the usual track gripping trip 5 may be pivoted therebetween, while the opposite end portions of Patented June 6, 1916.

said flanges are bent outwardly into down 7 wardly diverging relation as disclosed at 6. The portions 6 constitute cam faces for close contact with the walls of the usual peripheral grooves 7 in the wheels 8 of the litter carrier, whereby no matter if the sheath 1 be tilted, said sheath will be returned to its proper normal position when one of the wheels 8 comes into contact therewith. By so doing, the trip 5 andthe trip 9 mounted on the carrier will-always properly engage.

Another improvement resides in elongating the sheath 1 to such an extent as to allow the two trips 5 and 9 to contact while one of the wheels 8 stands upon the sheath. By so doing, regardless of the prevalence of wind, tilting of the sheath will be prevented until after the trips have accomplished their functions (see Fig. 1).

From the foregoing description, taken in connection with the accompanying drawings, it will be evident that the device will be highly efficient and durable, regardless of its simplicity, and that it will fulfil a long felt need in the art to which it relates.

In the present embodiment of the invention, I have shown one specific form of the device, but obviously I need not be restricted to the construction set forth since changes may be made within the spirit and scope of my invention. It will also be understood that the invention may be otherwise used than in connection with litter carriers.

I claim:

1. In a trip for application to the overhead tracks of carriers upon which the peripherally grooved wheels of the carriers travel, a sheath to be mounted slidably on the track and having a pair of downwardly diverging cam faces for contact with the head tracks of carriers upon which the peripherally grooved wheels of the carriers travel, a sheath to be mounted slidably on the track and formed of a single metal plate bent into the form of an elongated arch for the reception of the track, and a pair of downwardly diverging side flanges depending from opposite sides of the arch; in combination with a trip carried by the sheath. 4. In a trip for application to the overhead tracks of carriers upon which the peripherally grooved wheels of the carriers travel, a sheath to be mounted slidably on the track and formed of a single metal plate bent into the form of an elongated arch for the reception of the track, and a pair of side flanges extending downwardly from op-' posite sides of the arch and having clownwardly diverging cam portions at both ends; in combination with a trip carried by the sheath and disposed between the ends thereof.

5. The combination with an elevated track, a grooved wheel of a suspended carrier traveling on the track, and a trip carried by the carrier, of a sheath loosely mounted on the track, a trip on the sheath, and coacting means on the wheel and sheath to move the latter to normal operative position when engaged by the wheel.

6. The combination with an elevated track, a grooved wheel of a suspended carrier traveling on the track, and atrip carried by the carrier, of a sheath loosely mounted on the track, a trip on the sheath, and coa-cting means on the wheel and sheath to move the latter to normal operative position when engaged by the wheel, the sheath being of a length to permit the wheel to stand thereon when the two trips come into engagement.

7. A trip carrying device for swinging engagement with an elevated track, having a cam portion for engagement by the wheel of a carrier, whereby the trip will be automatically brought to its normal operative position.

8. The combination with an elevated track and a wheel of a suspended carrier thereon, of a trip carrying device loosely mounted on the track, and coacting means on the wheel and device whereby when the wheel engages said device the trip will be automatically moved to its normal operative position.

9. The combination with an elevated track and an elevated carrier having a wheel thereon, of a trip carrying device loosely mount ed on the track, a trip carried by said device, an additional trip on the suspended carrier for coacting with the aforesaid trip, and a cam on'the aforesaid device for moving the same to normal operative position when engaged by the wheel, the relation of parts being such as to allow the wheel to stand on the cam when the two trips come into engagement.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
